I''m trying to create a navigation which adds :class => "current" to the currently selected nav link (just like the WordPress nav). I presume the class would be determined by the controller params (which isn''t a problem as all my tabs are named after a controller). If so, how I would go about implementing this on the following example; <ul> <li><%= link_to ''Users'', users_path %></li> <li><%= link_to ''Posts'', posts_path %></li> <li><%= link_to ''Pages'', page_path %></li> </ul> I made some attempts at Googling this and subsequently came across a snippet on dzone, http://snippets.dzone.com/posts/show/1996 , but the plugin link appears to be dead. If only there was a ''link_to_class_current'' helper! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m happy with adding css class options to link_to - I just don''t know how to do this with conditional statements. For example, take the following URLs; /users/ /users/1 /users/1/posts (I appreciate this one may complicate things) For all those URLs, I would expect my nav to generate the following navigation (because the UsersController, or UsersPostsController, is in use); <ul> <li><%= link_to ''Users'', users_path, :class => "current" %></li> <li><%= link_to ''Posts'', posts_path %></li> <li><%= link_to ''Pages'', pages_path %></li> </ul> I have RailsBrain in my bookmarks but I haven''t found anything that specifically relates to my issue; the link_to family of methods don''t see to cover this.

Maybe it would help if you looked at my WordPress site: http://dotneil.com. You''ll see that the parent tab is given a "current_page_item", so when you hit the homepage, the ''Blog'' tab is highlighted.

link_to_unless_current supports this behavior quite nicely.
By default, it won''t make a link at all for the current action which
can be
quite nice, but the method supports a block that acts as the "unless"
condition as well.
<%=link_to_unless_current("Users", users_path) do
link_to("Users, :users_path, {:class=>:current})
%>
Or
<%=link_to_unless_current("Users", users_path) do
''<span class="disabled">Users</span>''
%>
Or however you see fit.

''current_page?'' may do the trick. I just realised the nav will use funky CSS dropdowns to contain more than one link per list item, which completely throws a spanner in things; <ul> <li class="current"><%= link_to ''Users'', users_path %></li> <li><%= link_to ''Posts'', posts_path %></li> <li><%= link_to ''Pages'', pages_path %></li> </ul> I just tried a quick ''n'' dirty route; <li class="<%= current_page?(:controller => :users) %>"><%= link_to ''Users'', users_path %></li> And I think I could get that working quite nicely if I can work out how to return "current" if true, nil if false, and also include multiple controller actions, too. Specifying the :controller without an :action only returns true if the current_page is the ''index'', which baffles me. This doesn''t work, but if I could do something like it, I''d be all set; <li class="<%= current_page?(:controller => :users, :action => {''show'', ''edit''}) do "current" %>"><%= link_to ''Users'', users_path %></li> Brian Hogan wrote:> link_to_unless_current supports this behavior quite nicely. > > By default, it won''t make a link at all for the current action which can > be > quite nice, but the method supports a block that acts as the "unless" > condition as well. > > <%=link_to_unless_current("Users", users_path) do > link_to("Users, :users_path, {:class=>:current}) > %> >Thanks Brian, the link_to_unless_current trick absolutely hits the previous requirements on the head. It''s just a shame that I may need to add the class="current" to the parent element instead.
